Is this still an issue? I'm not aware of an error in this combination...

there is still an issue with exact this combination.

So the profile fdp1 is the one using the search graph based on traditional TruckAttributes.BIN file?

Yes, the fdp1 profile uses the TruckAttributes.bin file in the re sub folder of the map like spd1 does. But fdp1 has a chData file which seems to can be handled by xRoute but not by xDima because the latter throws the above mentioned exception.
